PREFAB Unlock Tool:- Master key for all software

 Imagine a  computer program that would help anyone to edit inaccessible software like Microsoft Word and Apple iTunes, and even add customized features to them.

It is made possible by Researchers at the University of Washington.
The software would also help the user to move program from computer screens to mobile devices, which do not have a standard operating system.
It modifies pixels on a computer screen to change the behaviour of a program, such as Microsoft Word or Apple iTunes. The display is overridden and users are able to customize how they interact with the program.

This tool is called 'Prefab' .
This will allow users to customize their desktop in the same way people have been able to customize web pages. The research is outlined in the paper "Prefab: Implementing Advanced Behaviours Using Pixel-Based Reverse Engineering of Interface Structure.

Prefab, allows people to personalise programs based on their needs, according to the report that appeared online in Prefab takes advantage of the fact that almost all displays are made from prefabricated blocks of code such as buttons, sliders, check boxes and drop-down menus. The tool looks for those blocks as many as 20 times per second and alters their behaviour. It unlocks previously inaccessible interfaces and allows people to add the same usability tool to all the applications they run on their desktop.

It can also produce more advanced effects like creating multiple previews of a single image in Photoshop. For this, Prefab moves the sliders to different points, captures the output and then displays all of them on a single screen.
This could save time by showing a range of effects the user frequently adjusts.

The software would be demonstrated in Atlanta at the Association for Computing Machinery's Conference on Human Factors in Computing Systems.
